It has all the input modules - USB, Toslink, SPDIF as well as the Ballsie. It has the Metronome ASRC Module and the OTTO 2:1 I2S Switch module. It has both balanced and SE outputs. The case is 13x11.5x2 (approximate, in inches). The power switch is on the left and the selector switch is on the right, positions for the selector switch are: Optical (left), Coax (middle), and USB (right). I doubt you will ever blow the fuse that is currently installed but if you do you should use a 3 amp replacement fuse. The front plate hasn't been engraved with any markings, so you can add whatever lettering/indicator details you want.
The metronome is currently set to 192 khz.
This Opus was built in May 2008 by a friend, who is a semi-professional builder. It is very well built and very clean (see pics). The DAC chip is the older WM8740, but if you wanted to upgrade to the WM8741, you could just swap out the module. Sounds fantastic...it was mostly used via the USB module out of an iMac and fed a GS-X. The GS-X has since been sold...and I've slowly sold my balanced gear.
This is a great balanced DAC. Asking $450 shipped in the USA, which is much less than what the parts alone cost. Will split shipping for international...PM me for shipping quotes. Paypal fine. Please feel free to PM with any questions. Thanks...
UPDATE: I posted in the DIY section that the optical input was not working and needed some help troubleshooting the problem. Turns out that the module itself was fried. My friend, the original builder, attempted to fix it but it was beyond repair. A new toslink module from TPA is around $18. I haven't ordered one yet and was hoping that whomever wanted the opus could order one themselves and drop it into the chassis. No soldering involved, just clamping down the wires via the screws. Would literally take a few minutes. I can give more information on the correct wiring. I took pics of all the connections prior to removing the module.
I have been using the opus the last few weeks via both the USB input and the coax, and both work flawlessly.
I also have a couple of short balanced interconnects that I'll include with the opus...they're around 8 inches long. Neutrik connectors and mogami cable. Nothing fancy, but works fine.
